LIQUID CRYSTAL DISPLAY DEVICE APPRECIATING ROOM AND METHOD FOR APPRECIATING A LIQUID CRYSTAL DISPLAY DEVICE
First Claim
1. A liquid crystal display device appreciating room, comprising a room, a liquid crystal display device arranged inside the room and having a liquid crystal panel, and a light source which lightens the inside of the room, wherein a ¼
- wavelength plate is arranged on the front surface side of a viewing-side polarizer of the liquid crystal panel, the ¼
wavelength plate is arranged to set the angle of the slow axis direction thereof to 45±
5°
or 135±
5°
from the absorptive axis direction of the viewing-side polarizer toward the counterclockwise direction when the ¼
wavelength plate is seen from the viewing-side, and light inside the room is any one of left-handed circularly polarized light and right-handed circularly polarized light.

Abstract
Provided is a liquid crystal display device appreciating room making it possible to prevent glare or external-image-projection on the basis of external light so that persons can watch the screen of a liquid crystal display device satisfactorily. The appreciating room comprises a room, a liquid crystal display device arranged inside the room and having a liquid crystal panel 2, and a light source which lightens the inside of the room, wherein a ¼ wavelength plate 6 is arranged on the front surface side of a viewing-side polarizer 3 of the liquid crystal panel 2, the ¼ wavelength plate 6 is arranged to set the angle θ of the slow axis direction X thereof to 45±5° or 135±5° from the absorptive axis direction A of the viewing-side polarizer toward the counterclockwise direction when the ¼ wavelength plate is seen from the viewing-side, and light inside the room is any one of left-handed circularly polarized light and right-handed circularly polarized light.
